Abstract:
Alistipes spp is a genus of Gram-negative anaerobic rods involved in very few human diseases. We report the first case of abdominal infection due to Alistipes onderdonkii in a 58-year-old man with a history of chronic obstructive pulmonary disease. He presented with abdominal pain and general malaise after retrogastric drainage for a pancreatitis episode a few days earlier. After the diagnosis of diffuse peritonitis with perforation and necrotizing pancreatic collection, abundant pancreatic fluid was drained and yielded the isolation of A. onderdonkii in pure culture. Resistance to penicillin and moxifloxacin was documented for this strain. Treatment with metronidazole was prescribed, and the patient was discharged after improvement of his general condition.
Insights
A rare abdominal infection caused by Alistipes onderdonkii was identified in a patient with chronic obstructive pulmonary disease. This Gram-negative anaerobic rod showed resistance to common antibiotics, necessitating specific treatment.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Case Reports
Background:
- Alistipes spp. are Gram-negative anaerobic rods rarely implicated in human diseases.
- Human infections attributed to Alistipes spp. are uncommon, with limited understanding of their clinical significance.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
